the syntax is:
zfs set com.sun:auto-snapshot=[true|false]
or:
zfs set com.sun:auto-snapshot:<frequent|hourly|daily|weekly|monthly>=[true|false]
for example:
# zfs set com.sun:auto-snapshot=false zroot
Will disalbe all snapshots for zroot and all nested datasets will inherit the property.
# zfs set com.sun:auto-snapshot=true zroot/ROOT/default
Will enable all types of snapshots for given dataset.
# zfs set com.sun:auto-snapshot:weekly=true pool/var
Will enable only weekly snapshots for given dataset.
